{ "currentVersion": 10.91, "cimVersion": "2.9.0", "id": 2, "name": "Local Drainage Basin Direction", "type": "Feature Layer", "description": "Local Drainage Basin Direction is point data used to create directional arrow symbology that depicts the general direction of surface water flow within individual local drainage basins. Particular emphasis is given to directional arrows near the location of local drainage basin outlets. These and similar features along stretches of local drainage basin main stem basins and in coastal basins that drain into Long Island Sound are intended to aid in visualizing the network of local drainage basins in Connecticut. Point features are classified into three types - Outlet Direction, Main Stem Direction and Coastal Direction - and include an attribute that defines arrow direction. Data is compiled at 1:24,000 scale and should only be used for cartographic purposes on maps that also depict Local Drainage Basin Boundaries.\n\nThese data do not represent the exact location of basin outlets or stream confluences. Their position is largely based on the need to locate an arrow symbol near each local basin outlet such that it does not interfere or conflict with the placement of other information typically included on a basin map such as highways, local roads, bridges, waterbodies, political boundaries and geographic names. For this reason, some features may be farther away from the basin outlet than others. This information is not intended to accurately represent the hydrologic connectivity of surface water and were not automatically derived from or based on a hydrologic network such as the U.S.
